Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164786, here are decompositions:

19 + 164767 = 164786
43 + 164743 = 164786
79 + 164707 = 164786
103 + 164683 = 164786
109 + 164677 = 164786
163 + 164623 = 164786
199 + 164587 = 164786
283 + 164503 = 164786

Showing the first eight; more decompositions exist.
